During the breeding season, males behave aggressively, and females, on the contrary, are fearful.
For the period of spawning in the aquarium is placed large stone with a smooth surface, where the female will lay eggs. The male fertilizes the eggs, after which the female hides them in the mouth and bears them. Spawning process lasts about an hour.
During this time, the pair manage to postpone more than a hundred fertilized eggs. From them it turns out to deduce up to 60 fry.
Incubation period continues from 16 to 25 days, and all this time the female can not eat at all, becoming very exhausted and weak.
